A ducted micro quadcopter frame - the big brother of the tiny whoop!
I designed this to be a replacement frame for the QX90, but it can easily be built using individually sourced parts.
AUW with the configuration I've got is only 54g, exact same as the stock QX90!

Design is optimised for 0.4mm extrusion width.
Motor holes are designed to have an interference fit of ~0.3-0.5mm for a solid grip. The press tool goes on top of motor hole and then the motor placed at the bottom of the hole. This is then pressed together in a vise (motor shaft passes through small hole in the press tool) until the top of the motor is flush with the top of the motor hole.
8.0, 8.5, and 9.0mm motor hole models are included incase tolerances are too tight for your printer or you want to glue the motors.
~ From community feedback it seems that the 9mm model is best suited for the 8.5mm motors ~
